Analysis on Electromagnetic Field Leaked from Wireless Power Transfer System for Electric Vehicle Located at Case Study House

In recent years, toward the commercialization of the wireless power transfer (WPT) system for the electric vehicle, the associated technologies such as various transfer methods, coil configurations, operating frequencies, and the leaked electromagnetic fields have been discussed actively. In this paper, the leaked electromagnetic field distributions from the WPT system located around the case study house are presented. The attenuation characteristics by the wall of the house are measured at the real experimental house and calculated by using the electromagnetic field simulation. The result shows that the calculated and measured attenuation characteristics are almost in agreement with each other.
